Injected high modulus PU shaped with a profile that provides high level of impact and abrasion resistance. Featuring an additional insole (included in sizes 10-11-12-13-1-2-3-4) which has been specially manufactured to be one size smaller than the boots actual size. Allows the rider to initially wear the boot with the modified development insole until their foot grows sufficiently to use the standard insole, extending the life of the product.
